At least three people have been killed and one injured after a suicide bomber blew himself up near the entrance of the headquarters of Afghanistan’s national intelligence agency in Kabul, government officials told Reuters. There was no immediate claim of responsibility for the attack. It however comes a week after a group of Islamic State (IS, formerly ISIS/ISIL) terrorists attempted an attack on National Directorate of Security’s training center in Kabul, and were killed in an intense gunfight with police.
